The reception lens(10) and the laser beam output(11)
must not be covered during the measuring process.
Influences on the Measuring Range
The measuring range depends on the lighting conditions and
the reflective properties of the target surface.
For better visibility of the laser beam in bright extraneous light,
use the laser viewing glasses(13) (accessory) and the laser
target plate(12) (accessory), or shade the target surface.
Influences on the Measurement Result
Due to physical effects, incorrect measurements are possible
when measuring on various surfaces. These include:
– Transparent surfaces (e.g. glass, water)
– Reflective surfaces (e.g. polished metal, glass)
– Porous surfaces (e.g. insulation materials)
– Structured surfaces (e.g. roughcast, natural stone)
If necessary, use the laser target plate(12) (accessory) on
these surfaces.
Incorrect measurements are also possible on slanted target
surfaces.
Likewise, layers of air with different temperatures or indirectly
received reflections can influence the measured value.
Changing the Unit of Measurement
The default unit of measurement is "m" (metres).
Switch on the measuring tool .
Press and hold the button until the
menu for selecting the unit of measure-
ment is displayed.
Press the button to change the unit of measurement.
